Hi, I have an issue with my Auto Transmission and my mechanic does not have the appropriate scan tool software to ready the transmission codes. I know there is a manual procedure to read the codes but i can not find it anywhere on the internet. Does anyone know the procedure, otherwise i am going to have to take it to the Auto Trany Specialist to get it diagnosed. I believe it is one of the solenoids and I have a spare gearbox in the shed that I was going to get the soliniod from to replace in my current gearbox. Any help would be appreciated. Ryan

If you have 16 flashes, it's your duty solenoid C. I have that issue yet still haven't repaired it. Money
